I feel that'd maybe be going a bit far as other kinds of feed are also useful (e.g. by popularity, etc.), but I feel as a first step it should be mandatory for any platform to have to show in a human-readable way exactly why they showed you a piece of content. That allows for some intelligent feeds (users who watched this video watched these ones next most often) but without the addiction, manipulation, and nation-puppetting abilities currently enabled by the personalised algortihm.
